Abstract

The co-existence of hiss and chorus is frequently observed onboard satellites in the outer magnetosphere. The purpose of this paper is to investigate experimentally the association between hiss and chorus and to clarify the role of hiss in chorus generation. The paper is based on the detailed spectral analyses and direction finding measurements for the simultaneous occurrence of hiss and chorus observed onboard GEOS-1 satellite in the outer magnetosphere. The event analyzed here is observed near the equator (geomagnetic latitude, 6.8–8.5 degrees). Then, we propose the mechanism of hiss-triggered chorus based on our experimental findings.
